problem with wireless router

I have had a msft wireless router for a couple of years & it has worked
perfectly to use my laptop. I recently had to replace my hard drive &
software on my desktop due to a corrupted hard drive. I was having trouble
accessing the internet at all (I have a cable modem) due to a problem with ip
address recognition. I called my internet provider & they fixed the problem
with my cable modem. For some reason now when I have the wireless router set
up with my cable modem running through it I have no connectivity on my
desktop or laptop. If I run the cable directly from my desktop to the cable
modem my desktop works fine.
Can someone please help me with what the problem might be with my wireless
router & how to try to fix it.
Thank You!!!!

BTW. Microsoft stop selling Wireless Router years ago, if simple steps do
not work it might be the time for a fresh start with a new Router of modern
times.

Cable modems are usually configured to give out only one IP address
to a single device (MAC Addresss). In your case, that device happens
to be your desktop computer. When you connect your router to the
modem, the modem will refuse to give an IP address to it because it
thinks that your desktop is the only device it can assign the address
to.

Whenever changing devices connected to a cable modem, you usually
have to power down the cable modem by unplugging it from the wall
(never use the on/off button), then plug your new device (router)
into the modem, then plug the modem and router into the wall to power
them up again. Simply switching network cables rarely works.
